Electricsl Circuitd Flashcards
1
Q
What is the diagram for a resistor at constant temperature
A
In a straight line. At a constant resistance
2
Q
What does the diagram look like for a filament lamp and what does it do
A
It’s a wavy line and resistance increases at higher voltages
3
Q
What does the diagram look like for a diode
A
Very high resistance (no current until a specific voltage)
4
Q
What happens in a series circuit when you add resistors
A
The resistance increases
5
Q
What happens to the voltage in series circuits
A
They split between each component
6
Q
What is the voltage like in a parallel circuit
A
Is the same as the supply voltage
7
Q
What power stations are constantly running by the national grid
A
Nuclear and coal power stations
